\section{需从宽处拦\quad{}逼敌近坚垒}
\setcounter{tuxxx}{4}%图编号从5开始
{\heiti 题解}： 这两条要诀，主要强调了行棋的方向和充分发挥棋子的效力。\par
``需从宽处拦''适用于两种情况，一是对方分投时，要从宽的一边去拦；一是对方点三三时，要从广的一边去挡。\par
``逼敌近坚垒''是指使对方向自己坚垒处走棋。\par
图一中白1分投，图二中白1点三三，黑棋左边明显较右边宽广。\par

坚垒一词，使人首先想到如图三中黑\stone[\marktr]{black}坚壁，其实坚垒不只是指坚壁，凡是坚实已活的棋都是坚垒，如图四黑左边一块。\par
{\heiti 理由}：从广宽的一边去拦截投入己阵的敌子，可以避免重复，使自己具有更大的发展性。把敌子逼向自己势厚的地方，迫使对方走价值低的棋，则等于自己走了价值高的棋，这也是``逼敌近坚垒''的含义。\par

\tx ：本图黑2挡错了方向，白3长、5扳，由于左边是黑方大本营，不能让白出头，到黑12补时，白已先手活角，而黑\stone[\marktr]{black}一子离黑势太近，显得重复。\par
